The 2025 NBA Summer League in Las Vegas has been a showcase of emerging talent, but few have shone as brightly as Duke University’s trio of Cooper Flagg, Kon Knueppel, and Kyle Filipowski. Dubbed the “League Devils,” these former Blue Devils have taken the summer circuit by storm, proving why Duke remains a powerhouse in producing NBA-ready stars. With Flagg headlining as the No. 1 overall pick in the 2025 NBA Draft, Knueppel dazzling with his sharpshooting, and Filipowski earning MVP honours, the trio has left fans and analysts alike buzzing with excitement. Their performances signal a new era for Duke’s storied basketball programme, cementing its reputation as a pipeline to professional greatness.
Cooper Flagg, selected first overall by the Dallas Mavericks, made an immediate impact in his Summer League debut, despite a self-described “lackluster” shooting performance. The 18-year-old forward, known for his versatility at Duke, tallied 10 points, six rebounds, four assists, and three steals in a win against the Los Angeles Lakers, showcasing his all-around game. His highlight-reel plays, including a one-handed dunk and a crucial block in the clutch, underscored his potential as a future NBA star. Flagg’s ability to influence games beyond scoring, coupled with his competitive fire, has already drawn comparisons to Duke greats like Zion Williamson and Paolo Banchero.
Kon Knueppel, drafted fourth overall by the Charlotte Hornets, overcame early struggles to deliver a standout performance that solidified his case as a rising star. After an initial ankle issue limited his impact, Knueppel bounced back with a 16-point, 10-rebound, four-assist game against a Flagg-less Mavericks squad. His silky shooting stroke—honed at Duke with a 64.8% true shooting percentage—earned praise from none other than Klay Thompson, who predicted a bright NBA future for the young wing. Knueppel’s performance in the Hornets’ Summer League title run, capped by an MVP-calibre showing, has fans in Charlotte dreaming of a new era of success.
Kyle Filipowski, now with the Utah Jazz, stole the spotlight by earning the 2025 NBA Summer League MVP award, a testament to his dominance in Las Vegas. The big man averaged 9.6 points and 6.1 rebounds in his first NBA season, but his Summer League encore was even more impressive, with a 22-point, six-rebound outburst against the Philadelphia 76ers. Filipowski’s versatility as a scoring big, combined with his relentless energy, made him a fan favourite and a cornerstone for the Jazz’s future. His performances, alongside Flagg and Knueppel, highlighted Duke’s ability to produce players who thrive under pressure on the professional stage.
The Duke trio’s Summer League takeover is more than just individual brilliance; it’s a testament to the “Duke Brotherhood” that continues to shape the NBA. A viral Instagram post from the official Duke basketball account captured the trio dining with other Blue Devil alumni, showcasing the programme’s tight-knit culture. With five Duke players drafted in 2025, including top-10 picks Flagg, Knueppel, and Khaman Maluach, the Blue Devils’ influence in the NBA is undeniable. As Flagg, Knueppel, and Filipowski continue to cash in on their potential, the basketball world is witnessing the dawn of a new generation of Duke legends ready to dominate the league.
